I ran across an article at http://silvercrow.com/performance/oilcooler.htm that gave diagrams and a short description of using the engine guard for an oil cooler. Sounded like a good idea to me. It described using a Lockhart DP-180 thermostat between the engine and oil filter. That brought up two questions: Is it a good idea to start with and what are the drawbacks? And where would I get the Lockhart thermostat or something comparable? Can anybody help me?
